Description

Technical Field

[0001] The present application relates to the field of chemical cleaning technology, and in particular to an automatic cleaning device. Background Art

[0002] Chemical cleaning is a method of cleaning the surface of an object using a cleaning liquid. It can effectively remove dirt, sediment or other impurities on the surface of the object, and has been widely used in many fields such as industry, semiconductor manufacturing, and medical health. In related technologies, cleaning liquids usually use chemical agents such as acids, alkalis, organic solvents, chelating agents and surfactants, which are harmful to the environment and the human body. Therefore, when cleaning objects, the cleaning tank filled with cleaning liquid needs to be placed in a closed space to avoid the cleaning liquid from causing damage to the human body. However, in the process of cleaning objects, the cleaning liquid in the cleaning tank is likely to leak. Since the cleaning tank is in a closed space, it is difficult for the staff to detect the leakage of the cleaning liquid. When the staff discovers it, it often takes a lot of time to clean up the leaked cleaning liquid, which not only restricts the improvement of production capacity, but also easily damages the health of the staff. Utility Model Content

[0003] The present application provides an automated cleaning device, which aims to solve the problem in the related art that the cleaning liquid leaked from the cleaning tank cannot be processed in time and the processing efficiency is low.

[0004] In order to solve the above-mentioned drawbacks existing in the related art, the present application provides an automated cleaning device, which includes a frame, a central controller, a leakage pipe, a leakage valve, a waste liquid tank, a cleaning tank, a leakage detector, and a hollow box. The central controller, the box, and the waste liquid tank are all arranged on the frame. The cleaning tank is arranged in the box, and there is a bottom gap between the cleaning tank and the inner bottom wall of the box. The leakage detector is arranged in the bottom gap and is communicatively connected to the central controller. The leakage pipe is laid on the frame, one end of the leakage pipe is arranged in the bottom gap, and the other end is arranged outside the box and is connected to the waste liquid tank through the leakage valve. The leakage valve is communicatively connected to the central controller. Specifically, the cleaning tank is used to accommodate cleaning liquid; the leakage detector is used to detect whether there is cleaning liquid in the bottom gap in real time; the central controller is used to control the leakage valve to open to conduct the leakage pipe when cleaning liquid is present in the bottom gap; the leakage pipe is used to lead the cleaning liquid in the bottom gap out of the box and transport it to the waste liquid tank when the leakage valve is opened.

[0005] In some implementations, the automated cleaning device further includes a liquid storage tank, a liquid inlet pipe, a liquid discharge pipe, and a liquid inlet valve and a liquid discharge valve, each of which is communicatively connected to a central controller. The liquid storage tank is mounted on a frame, and the liquid inlet pipe and the liquid discharge pipe are both laid on the frame. One end of the liquid inlet pipe is mounted in the cleaning tank, and the other end is mounted outside the housing and communicates with the liquid storage tank via the liquid inlet valve. One end of the liquid discharge pipe is mounted in the cleaning tank, and the other end is mounted outside the housing and communicates with the waste liquid tank via the liquid discharge valve. Specifically, the liquid storage tank is used to store cleaning liquid; the liquid inlet pipe is used to conduct when the liquid inlet valve is opened under the control of the central controller, and to transport the cleaning liquid in the liquid storage tank to the cleaning tank; the liquid discharge pipe is used to conduct when the liquid discharge valve is opened under the control of the central controller, and to transport the cleaning liquid in the cleaning tank to the waste liquid tank.

[0006] In some implementations, the automated cleaning device further includes a high liquid level detector and a low liquid level detector, both of which are disposed on the inner sidewall of the cleaning tank and are respectively communicatively connected to the central controller. The high liquid level detector is located near the notch of the cleaning tank, and the low liquid level detector is located near the inner bottom wall of the cleaning tank opposite the notch. The cleaning liquid has a high liquid level state and a low liquid level state in the cleaning tank. The high liquid level state indicates that the liquid level of the cleaning liquid in the cleaning tank is consistent with the high liquid level detector, and the low liquid level state indicates that the liquid level of the cleaning liquid in the cleaning tank is consistent with the low liquid level detector. The high liquid level detector is used to detect in real time whether the cleaning liquid in the cleaning tank is in a high liquid level state. The low liquid level detector is used to detect in real time whether the cleaning liquid in the cleaning tank is in a low liquid level state. The central controller is also used to: when the cleaning liquid in the cleaning tank is at a high liquid level and the cleaning time of the cleaned object in the cleaning tank reaches a preset time, control the drain valve to open and the inlet valve to close; when the cleaning liquid in the cleaning tank is at a low liquid level, control the inlet valve to open and the drain valve to close; when the cleaning liquid in the cleaning tank is at a high liquid level and the cleaning time has not reached a preset time, control both the inlet valve and the drain valve to close.

[0007] In some implementation schemes, the automatic cleaning device also includes a one-way valve. One end of the drain pipe located outside the box is connected to the waste liquid tank through the one-way valve and the drain valve in sequence. The one-way valve is used to prevent the cleaning liquid in the drain pipe from flowing back during the process of the drain pipe transporting the cleaning liquid in the cleaning tank to the waste liquid tank.

[0008] In some implementations, one end of the leakage pipe outside the housing communicates with the drain pipe via a leakage valve, with the connection point on the drain pipe being between the one-way valve and the housing. Therefore, the leakage pipe is specifically configured to convey cleaning fluid from the bottom void into the drain pipe when the leakage valve is open, and then, after the drain valve is opened, convey the cleaning fluid, along with the cleaning fluid in the cleaning tank, to the waste liquid tank via the drain pipe.

[0009] In some implementations, the automated cleaning device further includes an air inlet motor, an exhaust motor, an air inlet duct, and an exhaust duct. A top gap is defined between the cleaning tank and the inner top wall of the housing. The air inlet motor and the exhaust motor are both mounted on a rack and are communicatively connected to a central controller. The air inlet duct and the exhaust duct are both laid on the rack. One end of the air inlet duct is positioned within the top gap, and the other end is positioned outside the housing and communicates with the air inlet motor. One end of the exhaust duct is positioned within the top gap, and the other end is positioned outside the housing and communicates with the exhaust motor. Specifically, the air inlet motor is configured to be activated under the control of the central controller to draw external air into the air inlet duct and transport it into the housing through the air inlet duct. The exhaust motor is configured to be activated under the control of the central controller to draw gas within the housing into the exhaust duct and transport it to the outside through the exhaust duct. The gas within the housing includes the air within the housing and the harmful gas within the cleaning tank.

[0010] In some implementations, the automated cleaning device further includes an air intake sensor and an air exhaust sensor communicatively connected to a central controller. The air intake sensor is disposed within the air intake duct and between the air intake motor and the housing. The air exhaust sensor is disposed within the air exhaust duct and between the air exhaust motor and the housing. The air intake sensor is configured to detect in real time the intake air volume generated by the air intake duct sucking in and conveying external air; the air exhaust sensor is configured to detect in real time the exhaust air volume generated by the air exhaust duct sucking in and conveying gas within the housing. The central controller is further configured to control the air intake motor and / or the exhaust motor to adjust the intake air volume and / or the exhaust air volume to normal when the intake air volume and / or the exhaust air volume are abnormal.

[0011] In some implementations, the automated cleaning device further includes an air inlet regulating valve and an exhaust regulating valve communicatively connected to a central controller. The air inlet regulating valve is disposed within the air inlet duct and between the air inlet sensor and the housing, while the exhaust regulating valve is disposed within the exhaust duct and between the exhaust motor and the exhaust sensor. The air inlet regulating valve is used to adjust the intake air volume; the exhaust regulating valve is used to adjust the exhaust air volume. The central controller is specifically configured to control at least one of the air inlet motor, the exhaust motor, the air inlet regulating valve, and the exhaust regulating valve to adjust the intake air volume and / or exhaust air volume to normal when the intake air volume and / or exhaust air volume are abnormal.

[0012] In some implementations, the automated cleaning device further includes an audible and visual alarm, which is mounted on the outer wall of the housing and communicatively connected to the central controller. The central controller is further configured to: control the audible and visual alarm to sound an audible and visual alarm when cleaning fluid is present in the bottom gap; or control the audible and visual alarm to sound an audible and visual alarm when the intake and / or exhaust air volumes are abnormal.

[0013] In some implementations, the ends of the air inlet and exhaust ducts located within the top gap are both separated from the cleaning tank and correspond to opposite sides of the cleaning tank. Furthermore, the automated cleaning device further includes an air direction adjustment plate located within the top gap, one end of the air direction adjustment plate being disposed on the inner top wall of the box and the other end being separated from the cleaning tank. The air direction adjustment plate corresponds to the middle portion of the cleaning tank, thereby blocking the air between the ends of the air inlet and exhaust ducts located within the top gap.

[0014] The automated cleaning device provided in the present application includes a central controller, a leakage pipe, a leakage detector, a leakage valve, a cleaning tank, a waste liquid tank and a hollow box. The cleaning tank is arranged in the box and is used to accommodate cleaning liquid. There is a bottom gap between the cleaning tank and the inner bottom wall of the box. The leakage detector is arranged in the bottom gap. One end of the leakage pipe is arranged in the bottom gap and the other end is arranged outside the box and is connected to the waste liquid tank through the leakage valve; wherein the leakage detector can detect in real time whether there is cleaning liquid in the bottom gap; the central controller can control the leakage valve to open to conduct the leakage pipe when there is cleaning liquid in the bottom gap; the leakage pipe can lead the cleaning liquid in the bottom gap out of the box and transport it to the waste liquid tank when the leakage valve is opened. Thus, although the cleaning tank filled with cleaning liquid is located inside the box, making it impossible for the staff to directly observe whether the cleaning liquid in the cleaning tank is leaking, the leakage detector set in the box can detect in real time whether the cleaning liquid in the cleaning tank is leaking (that is, whether there is cleaning liquid in the bottom gap), and the central controller will control the leakage valve to open to connect the leakage pipe when the leakage detector detects that the cleaning liquid in the cleaning tank is leaking, and the connected leakage pipe can transport the cleaning liquid leaked in the box to the external waste liquid tank. In other words, the present application can promptly detect the leakage of the cleaning liquid in the cleaning tank, and automatically perform the leakage treatment operation (that is, transfer the cleaning liquid leaked in the box to the external waste liquid tank) when the cleaning liquid in the cleaning tank is leaking, without the staff having to spend a lot of time to clean up the leaked cleaning liquid as in the traditional solution. This makes the present application more efficient in handling leakage, not only promoting the improvement of production capacity, but also ensuring the health of the staff.

DETAILED DESCRIPTION

[0018] In the related art, when cleaning objects with cleaning fluids, chemicals such as acids, alkalis, organic solvents, chelating agents, and surfactants are typically used as cleaning fluids. These are harmful to both the environment and the human body. Therefore, the cleaning tank containing the cleaning fluid must be placed in an enclosed space to prevent the cleaning fluid from causing harm to the human body. However, during the cleaning process, the cleaning fluid in the cleaning tank is likely to leak. Because the cleaning tank is enclosed, workers are unlikely to detect leaks. When workers discover the leak, they often need to spend a considerable amount of time cleaning the leaked cleaning fluid, which not only restricts productivity but also harms workers' health. Furthermore, during the cleaning process, harmful residual gases may remain in the cleaning tank. In this case, an exhaust system can be installed to exhaust the residual gases from the enclosed space. However, because the exhaust system has a fixed air volume, it is difficult to exhaust the residual gases in a timely manner, which can easily cause respiratory damage to workers. In view of this, the present application proposes an automated cleaning device in the following embodiments to address the above-mentioned drawbacks of the related art.

[0019] In order to make the purpose, technical solutions and advantages of the present application more obvious and easy to understand, the present application will be clearly and completely described below in conjunction with the embodiments of the present application and the corresponding drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. It should be understood that the embodiments of the present application described below are only used to explain the present application and are not used to limit the present application, that is, based on the various embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0020] See also Figure 1 , Figure 1 Schematic diagram of the structure of an automated cleaning device. This embodiment provides an automated cleaning device, including a frame (not shown), a central controller (not shown), a leakage pipe 105, a leakage valve 106, a leakage detector 104, a waste liquid tank 103, a cleaning tank 102, and a hollow box 101. The central controller, the box 101, and the waste liquid tank 103 are all arranged on the frame. The cleaning tank 102 is located in the box 101 and is mounted on the inner wall of the box 101. The notch of the cleaning tank 102 faces the box. 101, there is a bottom gap 1011 between the inner top wall of the cleaning tank 102 and the inner bottom wall of the box body 101, the leakage detector 104 is arranged in the bottom gap 1011 and is communicatively connected to the central controller, the leakage pipe 105 is laid on the rack, one end of the leakage pipe 105 is arranged in the bottom gap 1011, and the other end is arranged outside the box body 101 and is connected to the waste liquid tank 103 through the leakage valve 106, and the leakage valve 106 is communicatively connected to the central controller.

[0021] In this embodiment, the central controller mainly plays the role of control and data processing and analysis. All devices in the automatic cleaning device that are communicatively connected to the central controller, such as the liquid leakage detector 104, the liquid leakage valve 106 and the liquid inlet valve 110, the liquid discharge valve 111, the air inlet motor 117, the air exhaust motor 118, the air inlet sensor 119, the air exhaust sensor 120, the air inlet regulating valve 121, the air exhaust regulating valve 122 and the sound and light alarm 123 described below, etc., all need to work under the control of the central controller; preferably, the central controller includes a PLC (Programmable Logic Controller) system and an HMI (Human Machine Interface) system. In addition, the box body 101 of this embodiment is not completely closed. The box body 101 has a door (not shown). When the objects to be cleaned need to be placed in the cleaning tank 102 or taken out of the cleaning tank 102, the door needs to be opened. However, when the door is closed, a closed space for accommodating the cleaning tank 102 is formed in the box body 102.

[0022] Specifically, the cleaning tank 102 is used to accommodate cleaning liquid; the leakage detector 104 is used to detect in real time whether there is cleaning liquid in the bottom gap 1011; the central controller is used to control the leakage valve 106 to open when cleaning liquid exists in the bottom gap 1011 to connect the leakage pipe 105; the leakage pipe 105 is used to lead the cleaning liquid in the bottom gap 1011 out of the box body 101 and transport it to the waste liquid tank 103 when the leakage valve 106 is opened.

[0023] That is to say, although the cleaning tank 102 containing cleaning liquid is arranged in the box body 101, so that the staff cannot directly observe whether the cleaning liquid in the cleaning tank 102 is leaking, the leakage detector 104 arranged in the bottom gap 1011 can detect in real time whether the cleaning liquid in the cleaning tank 102 is leaking, that is, it can detect in real time whether there is cleaning liquid in the bottom gap 1011, and the central controller will control the leakage valve 106 to open when the leakage detector 104 detects that the cleaning liquid in the cleaning tank 102 is leaking, so that the leakage pipe 105 is turned on, and the turned-on leakage pipe 105 can transport the cleaning liquid leaked in the bottom gap 1011 to the external waste liquid tank 103. It is understandable that if the cleaning liquid in the cleaning tank 102 leaks, the leaked cleaning liquid will flow into the bottom gap 1011 under the action of gravity. Therefore, the leakage detector 104 is set in the bottom gap 1011. By detecting whether there is cleaning liquid in the bottom gap 1011, it can be known whether the cleaning liquid in the cleaning tank 102 leaks.

[0024] As can be seen from the above, the present embodiment can promptly detect leakage of the cleaning liquid in the cleaning tank 102, and automatically perform leakage treatment operations (i.e., transfer the leaked cleaning liquid in the box 101 to the external waste liquid tank 103) when leakage of the cleaning liquid in the cleaning tank 102 is detected. There is no need for the staff to spend a lot of time cleaning the leaked cleaning liquid as in the traditional solution. This makes the present embodiment more efficient in handling leakage, which not only promotes the improvement of production capacity, but also ensures the health of the staff.

[0025] In some embodiments, see Figure 1 In addition to the structure given above, the automatic cleaning device also includes a liquid storage tank 107, a liquid inlet pipe 108, a liquid discharge pipe 109, a liquid inlet valve 110 and a liquid discharge valve 111. The liquid storage tank 107 is arranged on the frame, and the liquid inlet pipe 108 and the liquid discharge pipe 109 are both laid on the frame. One end of the liquid inlet pipe 108 is arranged in the cleaning tank 102, and the other end is arranged outside the box 101 and is connected to the liquid storage tank 107 through the liquid inlet valve 110. One end of the liquid discharge pipe 109 is arranged in the cleaning tank 102, and the other end is arranged outside the box 101 and is connected to the waste liquid tank 103 through the liquid discharge valve 111. The liquid inlet valve 110 and the liquid discharge valve 111 are respectively communicated with the central controller. Specifically, the liquid storage tank 107 is used to store cleaning liquid; the liquid inlet pipe 108 is used to be connected when the liquid inlet valve 110 is opened under the control of the central controller, so as to transport the cleaning liquid in the liquid storage tank 107 to the cleaning tank 102; the liquid discharge pipe 109 is used to be connected when the liquid discharge valve 111 is opened under the control of the central controller, so as to transport the cleaning liquid in the cleaning tank 102 to the waste liquid tank 103.

[0026] That is to say, the central controller can control the opening / closing of the liquid inlet valve 110 and the opening / closing of the liquid discharge valve 111. When the central controller controls the liquid inlet valve 110 to open, the liquid inlet pipe 108 will be connected by the liquid inlet valve 110, and the cleaning liquid in the liquid storage tank 107 will be transported to the cleaning tank 102. When the central controller controls the liquid discharge valve 111 to open, the liquid discharge pipe 109 will be connected by the liquid discharge valve 111, and the cleaning liquid in the cleaning tank 102 will be transported to the waste liquid tank 103. Correspondingly, when the central controller controls the liquid inlet valve 110 to close, the liquid inlet pipe 108 will be blocked by the liquid inlet valve 110, and the cleaning liquid in the liquid storage tank 107 cannot be transported to the cleaning tank 102. When the central controller controls the liquid discharge valve 111 to close, the liquid discharge pipe 109 will be blocked by the liquid discharge valve 111, and the cleaning liquid in the cleaning tank 102 cannot be transported to the waste liquid tank 103.

[0027] It can be understood that when cleaning the object to be cleaned, the object to be cleaned can be immersed in the cleaning liquid in the cleaning tank 102. When the cleaning time of the object to be cleaned reaches a preset time, it can be considered that the cleaning of the object to be cleaned is completed. At this time, the cleaning liquid in the cleaning tank 102 needs to be replaced. The purpose is to prepare for the subsequent cleaning of other objects to be cleaned. The replacement of the cleaning liquid in the cleaning tank 102 can be achieved by the central controller controlling the opening / closing of the liquid inlet valve 110 and the liquid drain valve 111; usually, when replacing the cleaning liquid in the cleaning tank 102, the liquid drain valve 111 can be controlled to open first to discharge the cleaning liquid in the cleaning tank 102, and then the liquid inlet valve 110 can be controlled to open to introduce new cleaning liquid (that is, the cleaning liquid in the liquid storage tank 107) into the cleaning tank 102.

[0028] As one embodiment, the automated cleaning device also includes a high liquid level detector 112 and a low liquid level detector 113. The high liquid level detector 112 and the low liquid level detector 113 are both arranged on the inner wall of the cleaning tank 102 and are respectively communicatively connected to the central controller. The high liquid level detector 112 is close to the slot of the cleaning tank 102, and the low liquid level detector 113 is close to the inner bottom wall of the cleaning tank 102 opposite to the slot. The cleaning liquid has a high liquid level state and a low liquid level state in the cleaning tank 102. The high liquid level state indicates that the liquid level of the cleaning liquid in the cleaning tank 102 is adapted to the high liquid level detector 112, and the low liquid level state indicates that the liquid level of the cleaning liquid in the cleaning tank 102 is adapted to the low liquid level detector 113.

[0029] Specifically, the high liquid level detector 112 is used to detect in real time whether the cleaning liquid inside the cleaning tank 102 is in a high liquid level state. The low liquid level detector 113 is used to detect in real time whether the cleaning liquid inside the cleaning tank 102 is in a low liquid level state. The central controller is also used to: when the cleaning liquid in the cleaning tank 102 is in a high liquid level state and the cleaning time of the cleaned object in the cleaning tank 102 reaches a preset time, control the drain valve 111 to open and the inlet valve 110 to close; when the cleaning liquid in the cleaning tank 102 is in a low liquid level state, control the inlet valve 110 to open and the drain valve 111 to close; when the cleaning liquid in the cleaning tank 102 is in a high liquid level state and the cleaning time of the cleaned object in the cleaning tank 102 does not reach a preset time, control the inlet valve 110 and the drain valve 111 to close.

[0030] That is to say, in this embodiment, a high liquid level detector 112 is provided at a high position in the cleaning tank 102 (i.e., a position close to the slot mouth). When the liquid level of the cleaning liquid in the cleaning tank 102 corresponds to the position of the high liquid level detector 112, the high liquid level detector 112 is triggered, and it can be considered that the cleaning liquid in the cleaning tank 102 is full, that is, the cleaning liquid in the cleaning tank 102 is in a high liquid level state; further, in this embodiment, a low liquid level detector 113 is provided at a low position in the cleaning tank 102 (i.e., a position close to the inner bottom wall of the cleaning tank 102). When the liquid level of the cleaning liquid in the cleaning tank 102 corresponds to the position of the low liquid level detector 113, the low liquid level detector 113 is triggered, and it can be considered that there is no cleaning liquid or very little cleaning liquid in the cleaning tank 102, that is, the cleaning liquid in the cleaning tank 102 is in a low liquid level state.

[0031] It can be seen from this that the replacement process of the cleaning liquid in the cleaning tank 102 includes: when the cleaning liquid in the cleaning tank 102 is at a high liquid level and the cleaning time of the cleaned object in the cleaning tank 102 reaches a preset time, the central controller controls the drain valve 111 to open and the inlet valve 110 to close, the inlet pipe 108 is blocked by the inlet valve 110, the inlet pipe 108 cannot transport the cleaning liquid in the liquid storage tank 107 to the cleaning tank 102, the drain pipe 109 is connected by the drain valve 111, and the drain pipe 109 drains the cleaning liquid in the cleaning tank 102 The cleaning liquid is transported to the waste liquid tank 103, and the cleaning liquid in the cleaning tank 102 becomes less and less, and the liquid level gradually drops; when the liquid level of the cleaning liquid in the cleaning tank 102 drops to the position of the low liquid level detector 113, the cleaning liquid in the cleaning tank 102 enters a low liquid level state, the central controller controls the liquid inlet valve 110 to open, and the liquid discharge valve 111 to close, the liquid discharge pipe 109 is blocked by the liquid discharge valve 111, and the liquid discharge pipe 109 cannot transport the cleaning liquid in the cleaning tank 102 to the waste liquid tank 103, and the liquid inlet pipe 108 is opened by the liquid inlet valve 110. The liquid inlet pipe 108 transports the cleaning liquid in the liquid storage tank 107 to the cleaning tank 102. The cleaning liquid in the cleaning tank 102 is increasing and the liquid level is gradually rising. When the liquid level of the cleaning liquid in the cleaning tank 102 rises to the position of the high liquid level detector 112, the cleaning liquid in the cleaning tank 102 enters a high liquid level state. At this time, the objects to be cleaned in the cleaning tank 102 have not yet started to be cleaned or have just started to be cleaned, that is, the cleaning time of the objects to be cleaned in the cleaning tank 102 is much less than the preset time. The central controller controls the liquid inlet valve 110 and the liquid discharge valve 112. 1 are all closed, the liquid inlet pipe 108 is blocked by the liquid inlet valve 110, and the liquid discharge pipe 109 is blocked by the liquid discharge valve 111. The liquid inlet pipe 108 cannot transport the cleaning liquid in the liquid storage tank 107 to the cleaning tank 102, and the liquid discharge pipe 109 cannot transport the cleaning liquid in the cleaning tank 102 to the waste liquid tank 103. At this point, the cleaning liquid in the cleaning tank 102 is replaced. After the cleaning time of the subsequent objects to be cleaned in the cleaning tank 102 reaches the preset time, the next replacement of the cleaning liquid in the cleaning tank 102 will start, and the cycle will continue.

[0032] As one embodiment, the automated cleaning device further includes a one-way valve 114. One end of the drain pipe 109 located outside the housing 101 is connected to the waste liquid tank 103 via the one-way valve 114 and the drain valve 111. Specifically, the one-way valve 114 is used to prevent the backflow of the cleaning liquid in the drain pipe 109 during the process of the drain pipe 109 transporting the cleaning liquid in the cleaning tank 102 to the waste liquid tank 103.

[0033] That is to say, in this embodiment, a one-way valve 114 is provided on the drain pipe 109 between the drain valve 111 and the cleaning tank 102, so that the drain pipe 109 has a one-way drainage feature, that is, in the process of the drain pipe 109 transporting the cleaning liquid in the cleaning tank 102 to the waste liquid tank 103, the flow direction of the cleaning liquid in the drain pipe 109 can only be from the cleaning tank 102 to the waste liquid tank 103, and the cleaning liquid in the drain pipe 109 between the one-way valve 114 and the waste liquid tank 103 cannot cross the one-way valve 114 and flow to the cleaning tank 102, so that it will not hinder the drain pipe 109 from transporting the cleaning liquid in the cleaning tank 102. It can be understood that when the drain pipe 109 transports the cleaning liquid in the cleaning tank 102 to the waste liquid tank 103, the cleaning liquid in the cleaning tank 102 has cleaned the objects to be cleaned for a preset period of time. At this time, the cleaning liquid in the cleaning tank 102 will contain dirt, sediment or other impurities detached from the surface of the objects to be cleaned, that is, the cleaning liquid in the cleaning tank 102 is not clean. If this unclean cleaning liquid flows back from the drain pipe 109 to the cleaning tank 102, it will inevitably affect the subsequent cleaning of other objects to be cleaned. Therefore, this embodiment prevents this unclean cleaning liquid from flowing back from the drain pipe 109 to the cleaning tank 102, thereby ensuring the subsequent cleaning effect of other objects to be cleaned.

[0034] In addition, as mentioned above, one end of the leakage pipe 105 is disposed in the bottom void 1011, and the other end is connected to the waste liquid tank 103 via the leakage valve 106. Therefore, when the cleaning liquid in the cleaning tank 102 leaks into the bottom void 1011, the central controller can control the leakage valve 106 to open to open the leakage pipe 105, and the open leakage pipe 105 can directly transport the cleaning liquid leaked from the bottom void 1011 to the waste liquid tank 103. However, in this embodiment, the end of the leakage pipe 105 located outside the housing 101 can also be connected to the drain pipe 109 via the leakage valve 106, and the position on the drain pipe 109 that is connected to the leakage pipe 105 is between the one-way valve 114 and the housing 101. Based on this, the leakage pipe 105 is specifically used to transport the cleaning liquid in the bottom space 1011 to the drain pipe 109 when the leakage valve 106 is opened, and after the drain valve 111 is opened, the cleaning liquid is transported to the waste liquid tank 103 through the drain pipe 109 together with the cleaning liquid in the cleaning tank 102. It can be understood that if the cleaning liquid in the cleaning tank 102 leaks, the leaked cleaning liquid is usually a small amount, far less than the cleaning liquid in the cleaning tank 102. Therefore, when the cleaning liquid in the cleaning tank 102 leaks into the bottom space 1011, the conductive drain pipe 109 can transport the cleaning liquid in the bottom space 1011 to the drain pipe 109 for temporary storage, and then wait until the drain valve 111 is subsequently opened to be transported to the waste liquid tank 103 through the drain pipe 109 together with the cleaning liquid in the cleaning tank 102.

[0035] In some embodiments, see Figure 1 In addition to the structure given above, the automatic cleaning device also includes an air intake motor 117, an exhaust motor 118, an air intake duct 115 and an exhaust duct 116. There is a top gap 1012 between the cleaning tank 102 and the inner top wall of the box body 101. The air intake motor 117 and the exhaust motor 118 are both arranged on the rack and are respectively communicated with the central controller. The air intake duct 115 and the exhaust duct 116 are both laid on the rack. One end of the air intake duct 115 is arranged in the top gap 1012, and the other end is arranged outside the box body 101 and is connected to the air intake motor 117. One end of the exhaust duct 116 is arranged in the top gap 1012, and the other end is arranged outside the box body 101 and is connected to the exhaust motor 118.

[0036] Specifically, the air inlet motor 117 is activated under the control of the central controller to draw external air into the air inlet pipe 115 and deliver it to the housing 101 through the air inlet pipe 115; the exhaust motor 118 is activated under the control of the central controller to draw the gas inside the housing 101 into the exhaust pipe 116 and deliver it to the outside through the exhaust pipe 116; the gas inside the housing 101 includes the air inside the housing 101 and the harmful gases inside the cleaning tank 102. That is, during the cleaning process, the air inlet motor 117 and the exhaust motor 118 can be controlled by the central controller to cause the air inlet motor 117 to draw external air into the air inlet pipe 115 and deliver it to the housing 101 through the air inlet pipe 115, and to cause the exhaust motor 118 to draw the air inside the housing 101 and the harmful gases inside the cleaning tank 102 into the exhaust pipe 116 and deliver them to the outside through the exhaust pipe 116, thereby achieving effective air circulation and ventilation inside and outside the housing 101.

[0037] It is understandable that the cleaning liquid in the cleaning tank 102 is usually harmful and easy to volatilize, such as hydrochloric acid, sulfuric acid, nitric acid, sodium hydroxide, potassium hydroxide, etc. Hydrochloric acid evaporates to produce hydrogen chloride gas, sulfuric acid evaporates to produce sulfur trioxide gas, nitric acid evaporates to produce nitrogen dioxide gas, sodium hydroxide / potassium hydroxide reacts with carbon dioxide in the air to produce ammonia gas. These harmful gases produced will remain in the cleaning tank 102. If these harmful gases are not discharged from the box body 101, then when the subsequent staff opens the door of the box body 101 to replace the object to be cleaned, these harmful gases are bound to cause damage to the staff's respiratory tract. Therefore, this application discharges these harmful gases from the box body 101 by setting an air intake motor 117, an exhaust motor 118, an air intake pipe 115 and an exhaust pipe 116, so as to avoid these harmful gases damaging the staff's respiratory tract.

[0038] As one embodiment, the automatic cleaning device further includes an air intake sensor 119 and an air exhaust sensor 120 that are communicatively connected to the central controller. The air intake sensor 119 is disposed in the air intake duct 115 and is located between the air intake motor 117 and the housing 101. The air exhaust sensor 120 is disposed in the air exhaust duct 116 and is located between the air exhaust motor 118 and the housing 101. Specifically, the air intake sensor 119 is used to detect in real time the intake air volume generated by the air intake duct 115 sucking in and transporting external air; the air exhaust sensor 120 is used to detect in real time the exhaust air volume generated by the air exhaust duct 116 sucking in and transporting gas within the housing 101. The central controller is also used to control the air intake motor 117 and / or the exhaust motor 118 to adjust the intake air volume and / or the exhaust air volume to normal when the intake air volume and / or the exhaust air volume are abnormal. It can be seen that this embodiment can detect the size of the intake air volume and the exhaust air volume in real time by setting the intake air sensor 119 and the exhaust air sensor 120, reducing the frequency of manual detection of the intake air volume and the exhaust air volume, which reduces the labor cost to a certain extent and alleviates the work of the staff.

[0039] That is to say, the air intake sensor 119 can detect the intake air volume of the air intake duct 115 in real time and transmit it to the central controller, and the exhaust sensor 120 can detect the exhaust air volume of the exhaust duct 116 in real time and transmit it to the central controller. The central controller can determine whether the intake air volume and / or exhaust air volume are abnormal, such as comparing the intake air volume and exhaust air volume with their respective preset air volume ranges. When at least one of the intake air volume and exhaust air volume is not within the corresponding preset air volume range or deviates too much from the corresponding preset air volume range, the intake air volume and / or exhaust air volume can be considered abnormal. At this time, the central controller will adjust the intake air volume and / or exhaust air volume by controlling the air intake motor 117 and / or the exhaust motor 118 to make the intake air volume and / or exhaust air volume normal, thereby maintaining effective air circulation and ventilation inside and outside the box 101, and ensuring that harmful gases in the box 101 can be discharged in time. In addition, it should be noted that the central controller can adjust the intake air volume and / or exhaust air volume by adjusting the operating parameters of the air intake motor 117 and / or the exhaust motor 118, such as the speed, power and blade angle.

[0040] As one embodiment, the automated cleaning device further includes an air inlet regulating valve 121 and an air exhaust regulating valve 122 communicatively connected to the central controller. The air inlet regulating valve 121 is disposed within the air inlet duct 115 and located between the air inlet sensor 119 and the housing 101. The air exhaust regulating valve 122 is disposed within the air exhaust duct 116 and located between the exhaust motor 118 and the exhaust sensor 120. Specifically, the air inlet regulating valve 121 is used to adjust the intake air volume; the exhaust regulating valve 122 is used to adjust the exhaust air volume. The central controller is specifically configured to control at least one of the air inlet motor 117, the exhaust motor 118, the air inlet regulating valve 121, and the exhaust regulating valve 122 to adjust the intake air volume and / or the exhaust air volume to normal when the intake air volume and / or the exhaust air volume are abnormal. It can be seen that the air inlet regulating valve 121 and the exhaust regulating valve 122 of this embodiment are both electric regulating valves, and their opening and closing angles are automatically controlled by the central controller. The control of the opening and closing angles is more stable and precise than the manual form, and has high adjustability. By relying on the precise control of the opening and closing angles, the airflow in the air inlet pipe 115 and the exhaust pipe 116 can also be made more stable.

[0041] That is to say, when the central controller determines that the intake air volume and / or exhaust air volume are abnormal, the intake air volume and / or exhaust air volume can be adjusted not only by adjusting the operating parameters of the intake motor 117 and / or the exhaust motor 118 such as the speed, power and blade angle, but also by adjusting the opening of the intake regulating valve 121 and / or the exhaust regulating valve 122. This makes the adjustable range of the intake air volume and / or exhaust air volume wider, and the automatic cleaning device can also clean the objects to be cleaned within a wider air volume range. In short, by controlling at least one of the air intake motor 117, the exhaust motor 118, the air intake regulating valve 121 and the exhaust regulating valve 122, different air intake and / or exhaust air volumes can be achieved, which is convenient for meeting different air intake and / or exhaust air volume requirements; moreover, by controlling the air intake motor 117, the exhaust motor 118, the air intake regulating valve 121 and the exhaust regulating valve 122, precise adjustment of the air intake and / or exhaust air volumes can also be achieved, which can not only better maintain effective air circulation and ventilation inside and outside the box 101, but also can timely discharge harmful gases in the box 101 to prevent these harmful gases from damaging the health of the staff.

[0042] As one embodiment, the automatic cleaning device also includes a wind direction adjustment plate 124. The ends of the air inlet pipe 115 and the exhaust pipe 116 located in the top gap 1012 are separated from the cleaning tank 102 and correspond to the opposite sides of the cleaning tank 102 respectively. The wind direction adjustment plate 124 is located in the top gap 1012. One end of the wind direction adjustment plate 124 is arranged on the inner top wall of the box body 101, and the other opposite end is separated from the cleaning tank 102. The wind direction adjustment plate 124 corresponds to the middle part of the cleaning tank 102, which makes the wind direction adjustment plate 124 blocked between the ends of the air inlet pipe 115 and the exhaust pipe 116 located in the top gap 1012.

[0043] As the name suggests, the wind direction adjustment plate 124 mainly plays the role of wind direction adjustment. Blocking the wind direction adjustment plate 124 between the ends of the air inlet pipe 115 and the exhaust pipe 116 located in the top gap 1012 can prevent the air entering the box body 101 through the air inlet pipe 115 from being directly sucked into the exhaust pipe 116 by the exhaust motor 118. In this case, the air entering the box body 101 through the air inlet pipe 115 needs to bypass the wind direction adjustment plate 124 at the end close to the cleaning tank 102 before it can be sucked into the exhaust pipe 116 by the exhaust motor 118. The air entering the box body 101 through the air inlet pipe 115 will pass through the cleaning tank 102 in the process of bypassing the wind direction adjustment plate 124 at the end close to the cleaning tank 102, thereby carrying away the harmful gases in the cleaning tank 102. Subsequently, these harmful gases and air will be sucked into the exhaust pipe 116 by the exhaust motor 118 and transported to the outside through the exhaust pipe 116, thus realizing the discharge of harmful gases in the box body 101.

[0044] In some embodiments, see Figure 1 In addition to the structure given above, the automatic cleaning device also includes an audible and visual alarm 123 arranged on the outer wall of the box body 101 and communicatively connected to the central controller. Based on this, the central controller is also used to: control the audible and visual alarm 123 to sound an audible and visual alarm when cleaning liquid exists in the bottom gap 1011; or control the audible and visual alarm 123 to sound an audible and visual alarm when the intake air volume and / or exhaust air volume are abnormal. In other words, whether the leakage detector 104 detects that the cleaning liquid in the cleaning tank 102 has leaked into the bottom gap 1011, or the central controller determines that the intake air volume and / or exhaust air volume are abnormal, the central controller will control the audible and visual alarm 123 to sound an audible and visual alarm to alert the staff, so that the staff can be informed of the leakage of cleaning liquid and the abnormal air volume in a timely manner.

[0045] The above embodiments are only preferred implementations of the present application, and they are not the only limitations on the relevant contents of the automatic cleaning device; in this regard, those skilled in the art can flexibly set them according to the actual application scenarios based on the above embodiments. It can be understood that through the implementation of the above embodiments of the present application, the automatic cleaning device is composed of a central controller, a leakage pipe 105, a leakage detector 104, a leakage valve 106, a cleaning tank 102, a waste liquid tank 103 and a hollow box 101. The cleaning tank 102 is arranged in the box 101 and is used to accommodate the cleaning liquid. There is a bottom gap 1011 between the cleaning tank 102 and the inner bottom wall of the box 101. The leakage detector 104 is arranged in the bottom gap 1011. One end of the leakage pipe 105 is set The liquid leakage detector 104 can detect in real time whether there is cleaning liquid in the bottom gap 1011; when there is cleaning liquid in the bottom gap 1011, the central controller can control the leakage valve 106 to open to connect the leakage pipe 105; when the leakage valve 106 is opened, the leakage pipe 105 can lead the cleaning liquid in the bottom gap 1011 out of the box 101 and transport it to the waste liquid tank 103. It can be seen that although the cleaning tank 102 filled with cleaning liquid is located in the box body 101, so that the staff cannot directly observe whether the cleaning liquid in the cleaning tank 102 is leaking, the leakage detector 104 arranged in the box body 101 can detect in real time whether the cleaning liquid in the cleaning tank 102 is leaking (that is, whether there is cleaning liquid in the bottom gap 1011), and the central controller will control the leakage valve 106 to open when the leakage detector 104 detects that the cleaning liquid in the cleaning tank 102 is leaking, so that the leakage pipe 105 is turned on, and the turned-on leakage pipe 105 can transport the cleaning liquid leaked in the box body 101 to the external waste liquid tank 103. In other words, the present application can promptly detect leakage of the cleaning liquid in the cleaning tank 102, and automatically perform leakage handling operations when leakage of the cleaning liquid in the cleaning tank 102 is detected. There is no need for staff to spend a lot of time cleaning the leaked cleaning liquid as in traditional solutions, making the present application more efficient in handling leakage, which not only promotes the improvement of production capacity, but also ensures the health of the staff.
